CARD-CONTROLLED COUNTING MACHINE.

Anuman ma Ima s, 1m. seran 1ro. 540,751.

At the resent time, machines are in genor statistical work which utilize punched cards'to designate different statistical data. The points at which these cards are perforated are known as index points and they are commonly arranged in columns upon the cards. By the position o1 a perforated index point upon the column the desired data is designated. The cards are usually perforated in suitable punching machines and after perforation and comparison they are run through a sorti ng machine in` order to sort them into desire groups. `iThereafter it is the practice to run the cards through tabulating machines where the desired data is counted or accumulated upon suitable registers or counters.

In certain classes of statistica-l work it is desirable to count the number of ycards which contain index point perforations at a certain position upon the card. For example, it may be desirable to secure count of cards which have the sixth index point perforation perforated in the second column.

It is to this general end that the present invention is directed. Provision is made for receiving a stack of record cards, setting the machine for control upon any desired column and thereafter successively passing the cards through the machine. During the passage therethrough the machine will sense all cards which have, say the sixth index point, perforated in the second column and disclose upon a, suitable counter the total number of cards which have passed through the machine which are thus perforated.

The invention further contemplates the provision of means for counting all cards whether perforated or not passing through the machine and provision of means for counting all perforated cards.

, Furthe and more detailed objects of the invention will be set forth in further detail in the accompanying specification and mole F particularly spointed out in the appended claims and wn on the drawings which by way of illustration portray a preferred embodiment of the invention.

In the drawings:

Fig. 9 is a diagrammatic view `showing card feeding devices diagrammatically and the circuit diagram for the controlling magnets and relays when the machine is at the well known D position on the index.

Referring first to they diagrammatic Fig. 9, 10 designates a stack of record cards' which are fed one by one by means of a picker 11 to suitable upper feed rolls 12 whence the' cards are successively advanced through the lower rolls 13 to the discharge stack. not shown. The feed rolls and picker are all driven in unisomby the gearing and linkage shown diagrammatically in this iig ure. The drive to this gearing is secured through a shaft 15 which in turn receives wer from motor 24 by means "of suitable lt and ulleys. Rotating in unison with the card eed devices is a main tabulator or counter controlling shaft 19. This shaft is driven inv any suitable manner from the gearing which rotates the feed rolls.

In the card feed devices a common conductor bar 38 is provided together with a single sensing or tabulating brush 39. This brush is slidably adustable along its supporting shaft into a ignment with any desired index point column of the record cards which pass through the feeding elements. When a. perforation comes under the brush contact is established between the brushand devices are therefore provided with a card lever 50 which has a tip mounted in the path of the passing cards so as to be swung thereby to close contacts 52 and maintain lthe saine closed as long as cards are ted through the machine past the card lever.

- Referring to Fig. 3 the shaft 1S' extends across the machine under the counter assembly and is shoivn in dotted lines in this figure. This shaft through suitable gearing 2l drives the lower ot three shafts 22 Which in turn through the gearing shown in Fig. 2 drives two similar upper shafts These shafts carry cams 23 which constitute the restoring or operating' devices for the links to various counters. These counters are of the Well known Voeder type. Tabulating cards, as commonly used, have provision `for twelve index point perforations, corresponding to the index points designated 1 9, 0, X and R. Twelve counters 24 and two additional ones 25-26 are here provided, 25 being adapted to count the total ot all punched cards and 26 the total ot all cards Whether perforated or not. inasmuch as the drive for all these counters is identical, one only Will be described and the diderences in the magnetic control therefore will be later explained.

Referring to 7, counter 24 is provided with an actuating arm or link 27 which is normally restored to the right by the usual spring inside the counter. Link 27 connects with a pivoted hook member 28 having a shoulder adapted 'to engage cam 23 and an end portion adapted to be engaged by a latch 29 which forms the armature of a magnet 64. Upon the energization of this magnet the hooked member 28 is released and drops upon cam 23, thereby counting one upon the counter 24. Rotation of cam 23 restores t-he link 27 and at the proper time in the cycle magnet 64 having been deenergized, the hook 28 is relatched by the latch 29. To insure relatching of the armature or latch 29, a member 30 is provided which is actuated positively by a supplementary cam 3l mounted upon shaft 22 to mechanically knock the armature away from the magnet cores.

Also driven in unison with the shafts 22 is a cam shaft 32 (see Figs. 2 and 3). This shaft carries a number of cams forming part of cam contact devices 62 (best shown in diagrammatic Fig 9). Twelve of these cam contact devices 62 are provided one for each index point position together with three extra cam contacts marked 78. 72 and 66 in the diagrammatic ligure. The cam contacts 62 are timed to 0 erate successively just as the correspon ing index point comes under the brush 39. Y

Passing now to the diagrammatic view Fig. 9, a series of cards are placed in the stack 10. The brush 39 is selectively ad- )usted to theproper column and the roe- Leemans chine is then ready to count all the ones, the twos, threes, etc., in the cards which pass through the machine. It will be uuderstood that the ones are counted upon one counter 24, the tivos on another counter and so on.

To start the machine in operation, the switch 4Q leading to a source of current is first closed. Current now iiowvs through line 33 and the emergency stop key 42, now closed, through start key 4l, now closed, through motor relay 43, through motor 24 and back through line 34 to the other side of the line. The energization of motor relay 43 through its armature establishes a holding circuit traced as follows: from source through emergency stop key 42 to armature post of relay 45, Wire 46, cam contact combination 47, now closed, and back through the armature of relay 43, motor 24 to other side ot line. It may be here stated that the cam contact devices 47, 57, 48 and 49 are all individually insulated from each other and driven from a shaft which is geared to rotate in unison with the card feeding devices. The circuit heretofore traced holds the motor 24 in operation and permits the release of a start key.

ln all card-controlled machines the machine parts have a normal or home position. This position of parts and the corresponding card position is known as the D position of the machine. This D position is a position which the parts and cards take liust after one operation cycle has been completed and before another operation cycle commences. To indicate this position it is the common practice to mark a Wheel or index on the machine with the letter D and to provide a suitable pointer cooperating with this index Wheel. This wheel is used in timing the machine.

The cam contact devices 48 and 49 make at the 'so-called D card position. The circuits controlled by these cam contact devices are ineifective until a card passes under card lever 50 which causes a closure of contacts 52. Upon the closure of these contacts current is allowed to flow from source through line 33, cam contact device 48, thence through cam contact device 49, through line 51 tocard lever contacts 52, thence through armature binder post 53 of relay 54, through relay magnet 54, Wire 55, relay 56, and back through wire 34 to the other side of the line.

The energization of relay 54 establishes a circuit through its armature which through line 56l supplies current to the upper contact 49 thereby shunting out of circuit this cam contact combination. This circuit also shunts out of circuit the card lever contact 52 permitting the last card to ass through the xnachine'to the stacker. ntil relay 54 is energized the flow ot current to the upper tion its side of switch 40 from this relay is as follows: from relay 54, contacts 52, line 51, contacts 49 and 50, thence to line 33 and to switch 40. After the relay 54 is energized, this current flow through relay 54 can flow through line 56l to the `to of contact 49, thence back through 48 to ine 33 and back to 40. Thus the circuit just traced shunts card lever contacts 52 and cam contacts 49 and 48 out of control of the circuits previously controlled by them. Cam' contact device 57. works in conjunction with cam contact device 48 and serves to break the circuit to relays 54 and 56 once per card cycle, i. e., with contacts 57 and 48 both open there is no flow of current to line 56l and, consequently. 54and 49 are deenergized once per card cycle. The energization of relay 56 establishes a holding circuit for the main motor circuit by allowing current to flow through the armature of relay 45, thence through relay armature 56, now closed, through the armature of relay 43 and back through the motor, as previously expained. Relay magnet 56 thus maintains the motor 24 in operation when cam contact device 47 opens once per card cycle. After the passage of the last card, relay 56 will be deenergized permitting the machine to stop when ythe motor circuit is broken by cam contact device 47.

When relay 54 is energized. current is supplied to the common brush bar 38, and at the time of the passage of the index point perforations in the card under the brush, current will flow from the common bar 38 through brush 39 to line 60. This line 6() extends across and connects in parallel to the cam contact device 62. As heretofore explained, there is one of these cam contact devices 62 for each index point perforation position in the record card. Also these cam contact devices 62 are timed so as to make contact at* the time a corresponding perforation passes under the brush. 1f, for example, the #6 perforation passes under the brush, the cam contact device 62 above the #6 magnet will be closed just as this perforation passes the brush. Switches 61, which will be hereafter further described, being closed. the closure of cam contact device 62 establishes a circuit to a relay 63 energizing this relay and thereby establishing a locking circuit and also energizing selected magnet 64. Relays 63 are those commonly used in' tabulating machines and are known as the vmagnet relays. 'Ilheir purpose is to maintain the magnets energzed afterthe p :Q: ofit-he brush from e hole in the card. or a further descrip- V'tion of their operation see Hollerith Patent No. 945,236. This magnet 64 calls into acarticular counting device in the manner eretofore described. In connection with thedescription of Fig. 7, it will be understood that there is one of Athese magnets 64 for each index point position and for convenience in the dlagram Fig. 9 the relays 63 controlling their respective magnets 64 'have been individually numbered to correspond with the index point positions with which the magnets are adapted to operate. The circuit for the relays 63 will' be traced in detail hereafter. From magnets 64 (4 5-6-7-8-9 positions) current flows through a common line 65. through cam contact device 66, which has the function ofbreaking the circuit after any one of the above mentioned positionsare set for the adding operation.

'From this cam contact device the circuit ex# tends to a relay 67 and thence back through Wire 34 to the other side'of the line. from magnet 64 (R-X-.0*1-'2-3 positions) current flows throughia common wire "L to relay 67, and thence back'through wire 34 to the .other side of line. Cam contact device 72 breaks this circuit afterany` one of these mentioned positions are setfor adding operation. The cam contact device 72 breaks the circuit 65l by opening the supply circuits 73 and 68 for the holding relays correlated with magnets 64 (R-X-O-l- 2 3 positions). It will be understood that after cam contacts 62 open magnets 64 are supplied with current through the relays associated with the magnets. This cam con- Also tact device 7 2 has a further function to be described hereinafter. The circuit yfor relays 63 comprises two sections, 'one having 1") a common line 68 and the other having a common line 69. Line 68 extends to the contact point of the re'ay 70 and line 69 extends to post 53 of relay 54. Vhen the relay marked 6 of the sixty-three series is energized, relay 67 is energized also yand this latter relay is maintained energized by the energization of the relay 6 of the sixty-three series. Relay 67 attracts its armature and establishes a circuit traced as follows: from post 53 through wire ,71, cam-contact comination 72, now closed, back through wire 73'. wire 74, armature of relay 67, now closed. relay 70,'relay magnet75, reay magnet 76 tothe other side of the line. Relay 70, when energized, attracts its armature and establislies a holding circuit short-circuiting ywire 74. The circuit just traced through relays 70, 75 and 76 is indirectly used to control the total, card counter and the total punch card counter heretofore referred to. After this control issecured once per card cycle, cam contact 72 interrupts the circuit through wire 71. Relay 76. when energized, breaks a circuit which is used to control the ringing of a bell 77 and the stopping of the machine when a card having no hole perforated therein passes the control brush. This operation will be here after described.

The energzation of relay 7 5 and the attraction of its armature establishes a total punched card controlling circuit, traced as follows: from point 53 through wire 71, cam Contact device 78, now momentarily closed, wire 79, punched card counter controlling magnet 82, wire 81, armature of relay 75, now closed, total card counter controlling magnet 89, and baclr to the other side of the line. The above circuit, by the energization of the magnets 8O and 82 controls the stepping or advancing of the total punched card counter and of the total card counter 26 in the manner heretofore explained.

it a card which contains no perforation passes under the controlling brush 39 there will he no energization ot the relays 63 and 67. Therefore relays 70, 75 or 7G will not be energized and when cam Contact devices 78 close, a circuit is established as follows: from post 53 through wire 7 1, cam contact device 78, wire T9, reay 83, armature ot relay 75, switch 84. and hack to the right side or the line. Tf the switch 8l is thrown to the position shown, the punched cards are counted on both counters 25 and 26 controlled respectively by magnets 82 and 8O and the blank cards would not he counted at all.

T, on the other hand, the switch 84.- is thrown to the dotted line position, the magnet 82 will still remain out of circuit upon the passage of a blank card and its punched relay 76, switch 84, wire 5a. magnet 8O and bach to the other side of the line. Thus magnet 80 may be energized on the passage of each blank card as well as on the passage of each punched card and if switch 84 is adjusted to the position shown in full lines in the diagram the magnet 8O will be energized only on the passage of punched cards. Irrespective of the position of switch 84 magnet 82 will be energized only upon the passage of punched cards.

When 83 is energized on the passage of blank cards its armature is attracted, establishing a circuit traced as follows: from source through wire 33, stop key 42, post of start key el, through wire 86, through contact point and armature of relay 83, through relay 87 back through relay 45 to the other side of the line. Relay 87, when energized,

establishes the Yusual holding circuit through its relay to Wire 86 and keeps current flowmenace ing through 45 ater 83 becomes deenergized. This holding circuit of relay 87 also establishes a circuit through the bell 77 haelt to the line and keeps this bell ringing continually until the emergency stop key is depressed. The depression of this lrey opens circuit 86 thus deenergizing relay 87 and opens the bell circuit and thus stops the ringing of the hell. When relay 45 is energized its armature is attracted away from the contact breaking one of the holding circuits for the main motor relay 43. Thereafter upon the opening of the cam contact device 47 the one remaining holding circuit for the main motor relay 43 is interrupted thereby bringing the motor and the card feeding and counting device operated thereby to a stop.

las previously explained, the selection of the column upon which the count is to be made is secured by shifting the position of brush 39. In some cases it may he desir able not to count holes above a certain position in the index point column. For example, it may 'ce desired not to count passing cards having any holes which are numbered 1, 2, and 3. This result may be secured by opening the corresponding 1, 2 and 3 switches 61. If, for example, the three upper inde-X points are not to be counted the first three switches 61 from the left in the diagram are opened and the others left closed. If, on the other hand, the lower nine positions are not to be counted the first three switches are closed and the other nine opened. Any combination of these switches may be selected, as desired, thereby eliminating the counting of any particular index point position as desired from top or bottom of the card. In the machine, as constructed, the switches 61 are preferably in the form of canopy switches and one of these is shown in Fig. 2.

To reset counters 24 and 25 two resetting shafts 91n and 91 are provided. These shafts carry reset gears 92 which mesh with gears 93 which are disposed upon the individual counters so that upon the rotation of the shafts the counters 24 and counter 25 are reset to zero. To rotate shafts 91 and 91l a handle 90 is fixed on the end of shaft 91. To drive shaft 91 in unison with shaft 91, from shaft 91, gearing 91", 91 and 91d is provided. It follows that upon the rotation of the handle 90 all of the counters 24 and counter 25 are reset simultaneously. To ensure resetting, the .aring arrangement is such that one rotation of the handle 90 effects a double rotation of the shafts 91 and 91l and thus resets the counters twice to ensure accuracy of resetting.

The total punched card counter 25 is reset with the counters 24 and the total or all card counter 26 may or may not be reset-simultaneously with the resetting of the counters 24 and 25. To control whether this counter .Counter 25 is utilized to count all 26 is to be reset or allowed to go on accumulating, a lever 95 (Fig. 6) is rovided which rocks a shaft 96 (Fi 4). his shaft carries a cam block 97 w ich when in the position shown retains a shoulderedy pivoted plate 98 on 91 in upper position. With this position of the parts, gear 99 which revolves on a stud riveted into plate 98 is in mesh with oneof the reset gears 92 and this gear 99 through intermediate gear 100 free on shaft 91* will reset the counter 26 to zero. If, on the other hand, the lever 95 be thrown to lower `or accumulating position, cam block 97 will be rocked clockwise allowing plate 98 to swing downwardly under the power of rsprin 101 and disengage gear 99 from ear 92. pring 101 at its lower end is fixe to a plate carried on shaft 91 (see Fi 4)- Under these conditions the counter wil not be reset. To prevent the disengagement of the gear at improper times and to ensure their proper timing a Geneva stop interlock is provided. This consists of a disc element 102 havin an arcuate slot 103 which is fas-v tened to s aft 91. This disc element coopcrates` with a lockin ring 104 which is carried b shaft 96 w ich, as heretofore explaine is rocked by handle 95. These devices revent improper disengagement of the resetting devices for counter'26 at improper times. To prevent repeat resetting operation a latch 105 (Fig. 5) is provided which cooperates with a suitable pin carried by f handle 90.

From the foregoingit will be understood that the counters 24 may be utilized to count one per passing card per index point perforation. There is one counter 24 for each dierent index point perforation in a given column on the card. By adjusting the brush 39 the desired column may be selected. assing punched cards only. This counter is reset simultaneously with the resetting of the counters 24. Counter 26, on the other hand, is utilized for counting all cards whether punched or not and the resetting devices are of such nature that this counter may be reset at the end of a card group or may be allowed to o on and accumulate a total of the punched cards of the next up. The switch 84 is utilized to control t e operation of counter magnets 82.1ind 80. If this switch is in the .position shown in the diagram Fig. 9, the punched cards are counted on both counters 25 and 26, and the blank cards would not be counted at all. If, on the other hand, the switch is thrown to the dotted' line position the magnet 82 will be cut out of operation thereby rendering the punched card counter 25 ineffective when the card which is not punched passes under the sensing brush and a signal in the form of bell 77 is automatically rung and this signal is kept in operation even after the machine stops as previously described and until the emergency stop key 42 is depressed, thereby interrupting the bell circuit and the holding circuit.

After the last punched card passes through the machine and no more cards follow, the card lever 50 opens contacts 52 thereby opening the circuit to relays 54 and 56. Y In turn armature contacts of relay 56 open the first holding circuit to motor 24 and then cam contacts 47 open the second or last holding circuit for motor 24 and the machine will come to a stop automatically, but in no positive position, there being no clutch'or stop position on this machine.

Briefl summarized the operation and object of t c machine is as follows.

A group of record cards is placed in the stack. Some of these may be unched and others may be blank cards. lhe operator now places brush 39 on a selected index point column. If it is desired to count the number of cards perforated at all the index points in this column all the switches 61 are closed. If counting is not desired on all index point positions any selected switches 61 may be opened to suppress the countin on corresponding positions. The machin is now started inoperation by depressing start key 41. The counters 24 now tally, count or register the number of cards which ass through the machine with correspon ing point positions therein. Simultaneously with this o ration counter 25 counts, registers or tallies all passin punched cards irrespective of whether the index point perforations come in the index point column.

The counter 26 is also adapted to count the punched cards passing through the machine and if switch 84 is thrown to the dotted line sition this counter will also serve to count oth unched cards and passing blank cards. Shou d blank cards pass through the machine with the switch 84 in dotted line position a bell or audible signal will be sounded and the sounding of this signal maintained until the operator depresses the. emergency stop key 42, thus stopping the operation of the machine.
